The Uneven Nine Patch style of quilt block is so named because not all of the nine individual patches are the same size as is the case in a regular nine patch quilt block. This style of quilt block is often used in 10" quilt block to make the math easier, but you will find this construction method in many other quilt blocks as well.

I can't see the logic in the name Peony Basket for this quilt block, but then I was not the person who chose the name. So, that being said, this is a easy quilt block to make and perfect for those quilters who like 10" blocks. The components of this block are squares, rectangles and half square triangles -- all very common units and easy to work with.
